Interline Brands, a direct marketing and specialty distribution company, recently launched a new customer loyalty program that allows plumbing, HVAC, electrical and building contractors to earn American Airlines AAdvantage miles when they purchase products from the company's Barnett, Hardware Express and Leran brands.

Customers can earn up to 4,000 AAdvantage miles per month, based on reaching certain monthly net purchase volumes. The program started November 2004 and runs through 2005. Complete details of the program can be found at www.e-barnett.com, www.e-hardwareexpress.com, and www.e-leran.com.
